How is Jin?

"Yes, I've been in contact with Eira, but she doesn't seem to have been affected too much."

"Well, that's good to know. ...... but why is that woman so insubordinate?

You're not a spy, are you?

"I've made sure of that many times. It's just her personality, that's all.

I hope so. One of the complaints ...... seems to be a lack of material for research."

"But the way things are going right now, we can't even import what we want.

"And you think the zines will solve that?"

"Yes. Yes. In fact, the golem is being regenerated. <

Indeed it has.

Do not relax your surveillance. But fulfill any requests that will result in our benefit as much as possible.

Yes, sir.

I understand.

A few days after moving in, it was August, and Jin was beginning to spend his days doing research, as the name suggests.

"......It's difficult to configure this place, you know."

"Well, if we don't manage to connect ...... at least a series of connections, each one will run amok on its own."

"Can't we devise the shape of the base and place them at the shortest distance possible?"

Eira, Jin, and Cachea.

Cachéa is mainly supported by calculation. Eira comes up with the idea, and Jin takes it down to a practical level.

Jin and Cachier were already accustomed to Eira's foul mouth.

"It's hard not having magi crystals, isn't it?

"I heard that this continent is poor in mineral resources to begin with. I don't know if that's the reason, but there are no demons either.

Eira gave me an interesting piece of information.

"No demons?　Not even one?"

"Yes. There hasn't been a confirmed one for at least 300 years."

"Hmm. ......"

Jin let his imagination run wild.

< migrated to Ars, they filled the planet's core with superheavy matter in order to create the same gravity as that of Hale.

What did they do with the large amount of magical crystals (magi-crystals) that they used in that process?

Jin thought that this continent might have been the source of the crystals.

< would be able to dig out the magi crystals from the ground.

I don't know what kind of relationship this has with demons, but what if the existence of magi crystals has a close relationship with the ecology of demons?

I thought of such a hypothesis, but being unfamiliar with biology, I could not think beyond that.

"....... Hey, Jin!　Are you listening to me?"

Eira's voice interrupted Jin's thoughts.

"Yes, I'm listening. I've been thinking about something for a while now. I was wondering if we could use magic circle instead of ...... magic crystals."

"Huh!　How could such a foolish thing ...... be possible?"

"Well, I don't know, but if Jin-san says it can be done, then it can be done.

Jin looked at them alternately and then slowly opened his mouth.

"The magic circle is all about the written <>. It is true that if a <> magic circle were written on a piece of paper and activated on the spot, the paper would burn. That is why the <> is so important."

"Well, I understand what you are saying, but ...... it is inevitably <>, isn't it?"

Eira is aware of the same shortcomings of the magic circle as Jin and is concerned about them.

"That's right. But it depends on how you use it.

"Use? ......"

Yes. It's not suitable for operating the golem, but what about the mana stand we fixed last time?"

Eira nodded in understanding.

"That's right. It is not required to be fast!"

"We can take out the control core from such a magi-machine and attach a magi-board with a magic circle engraved on it instead.

"That saves on the magi crystals. I think we need to get permission from ......."

Katya looks worried.

"That's right. I don't know what will happen if they find out.

When Jin nodded, Eira added,

"The penalties for criminals are very severe in this country.

Eira said threateningly, "This country has strict penalties for criminals.

Putting aside the issue of crime, Jin and his group started researching to realize their idea.

"Paper is out of the question for engraving magic circle, but can we use any metal?"

"No, it should be easier to transmit magic power. I think an alloy with a little mithril silver added would work."

"So, it would be ...... better to use an inexpensive metal for the base, right?　How about bronze?"

Kachair seems to have such a market in mind and is very reliable in such a case.

"Bronze would be fine."

"Okay, then. ......."

Their teamwork was better than expected.

* * * * *

What?　What?　...... that will save the magic crystals (magi crystals)?　Really?"

When he had some idea of what to expect, he told Paelova about it.

"It seems there is nothing to worry about."

"Yes. But it is still too early to say for sure. But it is too early to say for sure. ...... Give permission for the modification of the mana stand.

huh?

* * * *

Permission granted.

"Okay, let's start modifying it."

Jin and Eira, accompanied by Hope, went to the mana stand that was to be remodeled.

The modification was completed as planned.

"Now we have two used magecrystals.

One used for the ether converter and the other used for the control core to control the vending machine.

"Yes, that's right. Jin's idea has come to fruition.

"At this rate, if we modify every mana stand in town, we should be able to get at least ten of them.

"Then you'll be able to make all kinds of things.

"I'm looking forward to it, Jin!"

Eira smiled unusually.

"We'll go back today and have another study session. "I'm looking forward to it, Jin!" Eira said with a rare smile.

"Yes, yes, of course."

Eira was not only dour, but studious and curious about new ways to use ......<>.

Unfortunately, her aptitude is low and she is unlikely to learn more than the elementary level.

Still, they were more enthusiastic than others, and with KaChea in the group, <> had become a daily routine for the three of them.

"Well, what shall we do today?

"We'll continue where we left off yesterday, won't we?

"Yes, I think so. Jin, make the magic circle smaller and faster. This is fun.

And you too, Katya...

I'll do my best.

The three of them were becoming a good team.

It was mid-summer. A hot wind is blowing through Lawhon.
